During an asthma attack, symptoms may range from a mild whistling or hissing sound as you breathe to severe obstruction of the airways, potentially causing a life-threatening inability to breathe. Cough-variant asthma begins as persistent, chronic cough without shortness of breath. Although asthma can be serious, there are many ways to prevent and control symptoms.

The underlying cause of asthma is two part: 1) inflammation in the lining of the lung, and 2) structural changes in the lung due to inflammation and narrowing of air passages. Factors in indoor and outdoor environments, called triggers, can make asthma symptoms worse and cause asthma attacks in people who have asthma.

Known asthma triggers include:

Allergens:

Pollen

Mold

Animal dander—fine scales from skin, hair, or feathers

Dust mites

Cockroaches

Viral infections of the respiratory tract

Irritants:

Strong odors or sprays

Chemicals, including preservatives containing sulfites and dyes which are in many foods
